Decoy (formerly Double)

jQuery plugin to make decoys for your elements.

Ever wished to change an element's properties, style and behavior and instantly restore to what it was before the mess ? That's what Decoy enables you to do. You make a decoy, change it, and then, eventually, restore the original.

Usage:

var box = $('#box');

box.css('background', 'black'); // We set its background to black
box.decoy().css('background', 'red'); // Now it has a red background, but we are actually looking at its decoy
box.restore(); // Here we recover the original, restoring its background to black

The method decoy() is a reference to the element's decoy. You can chain multiple calls just like you do with regular jQuery objects. That's because it is a regular jQuery object.

box.decoy().text("Hello, I'm a decoy!").css('font-size', '48px');
box.decoy().text("I do dangerous stuff for you.");

Whatever changes you've done to its decoy, it will be undone when you restore the original. All styles and bindings, everything back to what it was before the first time you called decoy() on it.

Note:

The plugin has been renamed to Decoy since double is a reserved word and would cause trouble in the future.
